http://jelastic.com In this tutorial we will see how Jelastic automatically adds vertical scalability to any application with no code changes required. As application load increases, Jelastic can automatically detect that and add memory and CPU resources that application needs to cope with demand. When load goes down, Jelastic recycles the resources back thus reducing the developer costs.
Unlike horizontal scalability, vertical scaling does not require application code and architecture changes. Jelastic implements this mechanism automatically thus saving your time and money.
Jelastic is next generation Java hosting platform which can run and scale *any* Java, PHP, Ruby, Node.js or Python application. Try it free at http://jelastic.com
